当数据包含空格时，PHP post不起作用

$data = "包含 空格";
$encodedData = urlencode($data);

// 创建POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/post-endpoint");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "data=" . $encodedData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// 执行请求并获取响应
$response = curl_exec($ch);
curl_close($ch);

// 处理响应
if ($response === false) {
    echo "POST请求失败";
} else {
    echo "POST请求成功，响应内容：" . $response;
}
